Cyber attacks on small businesses happen for a simple reason: small businesses hold data that is just as valuable to criminals as what a large enterprise holds, but they typically defend it with far fewer resources. According to Verizon's 2025 Data Breach Investigations Report (DBIR), an annual analysis of confirmed data breaches worldwide, 43% of cyberattacks now target small businesses. Customer records, payment card numbers, and employee Social Security numbers sell for $150 to $1,000 per record on dark web marketplaces. The value is there. The defenses usually are not.
If your business handles customer data, accepts payments, or employs even a handful of people, that calculation applies to you directly.
Quick Answer
Small businesses get hacked because they hold the same valuable customer and financial data as large companies but run weaker defenses, fewer staff, slower patching, and little monitoring to catch an intrusion early. Verizon's 2025 DBIR found that 43% of cyberattacks now target small businesses, and IBM's 2025 Cost of a Data Breach Report puts the average breach cost for a small business between $120,000 and $1.24 million. Most of these breaches trace back to four entry points: phishing, ransomware, business email compromise, and unpatched software. Five controls, MFA, automated patching, email filtering, employee training, and tested backups, close most of that gap for roughly $500 to $3,000 a year at a 10-person business.
The Four Attack Paths Behind Most Breaches
According to Verizon's 2025 DBIR, four entry points account for the large majority of breaches at small businesses. Phishing and credential theft lead at 36%: attackers impersonate banks, vendors, or executives to steal passwords, then log in using those legitimate credentials. Ransomware follows at 28%, often arriving through phishing, exposed remote access tools, or unpatched software, and increasingly paired with threats to publish stolen data if the ransom goes unpaid.
Business email compromise (BEC) drives 18% of financial losses. The FBI's Internet Crime Complaint Center reported $2.9 billion in BEC losses in 2025, with small businesses accounting for 64% of victims and an average theft of $180,000 per incident. The remaining share traces to exploitation of unpatched software, a problem compounded by small businesses taking an average of 97 days to apply security patches while attackers begin exploiting new vulnerabilities within about 7 days of disclosure, according to the CISA Known Exploited Vulnerabilities (KEV) catalog.
Five Controls That Close Most of the Gap
A small business doesn't need an enterprise budget to cut its risk substantially. Implementing five controls correctly can deliver roughly 80% risk reduction, for an estimated $500 to $3,000 a year at a 10-person business. Multi-factor authentication (MFA) is the highest-return control: it blocks the large majority of automated credential attacks and costs nothing beyond an authenticator app. Our guides on password security and endpoint detection and response (EDR) for small business cover two of these controls in more depth.
Where to Start
- Enable multi-factor authentication on email, banking, accounting, and remote access accounts
- Turn on automatic updates for all workstations and servers, and review business applications weekly
- Filter email and authenticate your domain with SPF, DKIM, and DMARC to block phishing and spoofing
- Run annual security awareness training plus periodic phishing simulations for employees
- Back up data daily using the 3-2-1 rule and test restoration every quarter
What a Breach Actually Costs
The average cyberattack costs a small business between $120,000 and $1.24 million, according to IBM's 2025 Cost of a Data Breach Report, covering incident response, downtime, customer loss, and regulatory fines. The same report found that businesses with fewer than 500 employees pay $164 per compromised record, more than the $148 enterprises pay, because fixed response costs get spread across a smaller revenue base. Businesses that handle regulated data face added exposure: HIPAA violations can carry fines up to $1.5 million a year for small healthcare providers, and FTC Safeguards Rule violations carry penalties up to $100,000 per violation.
Monitoring catches what prevention misses
MFA, patching, and backups reduce risk, but someone still has to watch for the intrusions that get through. Bellator Core bundles managed EDR, remote monitoring, and Ransomware Rollback for $33 per computer per month; Bellator Shield covers EDR alone at $19.

Frequently Asked Questions
Small businesses hold the same kind of valuable data as large enterprises, customer records, payment information, employee Social Security numbers, but typically run with less security staff, weaker access controls, and no monitoring to catch an intrusion quickly. Automated scanning tools can identify an exposed, unpatched system within minutes of a new vulnerability going public. Without monitoring or a documented incident response plan, the gap between a breach starting and a business noticing it can stretch for months.
According to Verizon's 2025 Data Breach Investigations Report, 43% of cyberattacks now target small businesses. That share has grown as attackers increasingly favor less-monitored targets over hardened enterprise networks.
The average cyberattack costs a small business $120,000 to $1.24 million, according to IBM's 2025 Cost of a Data Breach Report. The same report found small businesses pay $164 per compromised record, more than the $148 per record larger enterprises pay, because fixed incident response costs fall on a smaller revenue base.
Multi-factor authentication delivers the highest return for the lowest cost. It blocks the large majority of automated credential attacks and, for most small businesses, costs nothing beyond installing an authenticator app on accounts that already support it. Start with email, banking, accounting software, and remote access tools.
